Low-cost accelerometry-based posture monitoring system for stroke survivors

This paper reports a low-cost autonomous wearable accelerometry-based posture monitoring system for stroke survivors. The hardware part of the system consists of monitoring devices, each of which comprises of a three-axial accelerometer and a beeper, LED light and vibrator to provide redundant modes of inappropriate posture warnings that would hopefully trigger self-correction. The inappropriate posture data are stored in an EEPROM. The software part of the system downloads, analyzes and presents the data in graphical format to enable a carer or therapist to quickly glance at the durations, frequency and locations of inappropriate postures.
